Title: Position measuring apparatus
Inventor: TOUKI TATSUHIKO
IPC: G03F9/00
Filed: 1990-11-30
Abstract: PURPOSE:To prevent generation of measuring errors resulting from the dislocation or the like of the plane of linear polarization and to improve the measuring accuracy by using a laser which is polarized at random for a laser source of a position measuring apparatus. CONSTITUTION:The light from a laser source 11 which emits random polarized lights is brought to two acoustoptical elements 14a, 14b. The incident light (frequency f0) is modulated to f0+f1 by the element 14a, while the incident light is modulated to f0+f2 by the element 14b. The modulated light is cast to an object to be measured or the like. At this time, since the random polarized laser is used as the light source 11, even when the two luminous fluxes from the elements 14a, 14b are used for the optical heterodyne detection, non-linear errors are never brought about, thus ensuring highly accurate detection. Moreover, when the apparatus is applied to the alignment in an exposure apparatus, the alignment light incident upon the wafer surface averages the phase errors at the resist, etc., owing to the random polarized light, so that the alignment accuracy is improved.

Title: Integrated circuit for oscillation and oscillator circuit
Inventor: HASEGAWA EIICHI
IPC: H03B5/32
Filed: 1993-12-27
Abstract: PURPOSE:To improve oscillation start, to suppress the deterioration of the duty of the oscillation output at the time of steady state oscillation and to reduce current consumption. CONSTITUTION:The change circuit 7 receiving the output of the detector circuit 6 detecting an oscillation initial state lowers the inversion potential of an inverter 1, increases mutual conductance and makes oscillation easy. Because the inversion potential is lowered than the inversion potential of an inverter 5 at this time, the output of the inverter 5 is held at an 'H'. When an oscillation detector circuit 6 detects a steady state oscillation, the change circuit 7 is interrupted from an oscillation part OSC and the oscillation of the oscillation part itself is performed. At this time, the inversion potential of the CMOS inverter 1 of the oscillation part OSC and the inversion potential of the CMOS inverter 5 for output buffer are equal, the duty of oscillation output is not deteriorated and current consumption is also suppressed. Because sufficient negative resistance can be obtained at the oscillation initial state, the feedback resistance 3 of a low value can be used.

While the coating of the paint containing conductive carbon black is not especially specified, an effective magnetically shielding material is obtained even in a small amount of coating. The coating quantity converted into a film thickness after drying is about 5-95μm, preferably about 10-20μm. In the case of forming this paint film 2, primer layers can be formed previously on the surfaces of the paint film 2 and the base material 1. Thereby, a high shielding quality from electromagnetic waves is obtained by an extremely thin metallic film.
